Antimatter delivery is solving a cosmic mystery
Matter and antimatter should have destroyed each other at the Big Bang. See how CERN’s mobile labs are probing why our universe exists at all.

We are essentially manufacturing the rarest substance in existence to see if the mirror of reality has a tiny, hidden crack in it. If matter and antimatter are perfectly symmetrical, then we shouldn't be here.

Antimatter is being produced but for what purpose

The CERN "Antimatter Factory" is an environment of extreme physical activity where protons are smashed into metal targets at near-light speeds. This process requires massive electrical systems and magnets that create significant "magnetic noise," which interferes with the incredibly delicate measurements needed to study antimatter. By transporting the particles at a cautious speed to a quieter, shielded laboratory away from the accelerators, researchers can achieve the precision necessary to observe subtle signals and fundamental symmetries.
Antimatter cannot be held in a physical jar because it annihilates instantly upon contact with regular matter. Instead, scientists use a device called a Penning trap, which utilizes powerful electromagnetic fields to suspend the particles in the center of a vacuum. To ensure the particles remain stable during transport, the vacuum must be sparser than the void of space to prevent collisions with stray air molecules, and the container must be cooled to near-absolute zero using liquid helium to prevent the particles from becoming too "hot" and escaping the magnetic grip.
The theory, rooted in Paul Dirac’s 1928 equations, suggests that for every particle of matter, there is a twin antiparticle with identical mass but opposite charge. According to the Big Bang theory, the universe should have created equal parts matter and antimatter, which should have annihilated each other and left the universe as nothing but light. Scientists study antimatter to find a "crack in the mirror"—a tiny discrepancy or asymmetry—that explains why matter won out and allowed stars, planets, and humans to exist.
Antimatter is considered the ultimate fuel because matter-antimatter annihilation converts one hundred percent of mass into energy, making it ten billion times more powerful than chemical combustion. While current chemical rockets would take tens of thousands of years to reach the nearest star system, an antimatter-powered "beam-core" rocket could theoretically reach ten to forty percent of the speed of light. This would allow humans to reach other solar systems within decades rather than millennia, effectively breaking the "tyranny of the rocket equation."
Yes, antimatter is already a vital tool in modern medicine through Positron Emission Tomography, or PET scans. In this procedure, positrons (the antimatter twins of electrons) are used as biological tracers. When these positrons annihilate with electrons inside a patient's body, they release gamma rays that allow computers to map internal biological processes. This technology is used daily to detect tumors and help scientists understand the inner workings of the human brain.
